I use Pertronix ignition modules in my ’48, Autolite (7 years), and ’54 Delco (10 years) equipped Packards, both are 6+ systems. I think we have to go back to the recent discussion on the size of battery cables. Ultimately something will limit the ability to start an engine, and voltage drop becomes more important if Pertronix equipment is installed. My experience is; if the starting and charging portion of the electrical system is maintained, then the performance of the Pertronix equipment is acceptable. I also have a Pertronix ignition in my ’30 Model A (17 years), but that car has been converted to 12-, so other than system reliability no other comparisons can be made. Our local Model A expert will frequently add that if the car is equipped a Pertronix ignition and an alternator you better know that they isn’t a lot of AC ripple in the DC alternator output, although I have not independently confirmed that concern.

I’ve got 34 combined years of use with these ignition systems and have not had an occurrence to question their proper operation . . . but none of this experience is at an outside air temperature where the battery capacity would be in question. It’s a buy, install, and forget item . . . I wish I could say the same about carburetors. I also question whether the industry has a source of reliable condensers for the traditional ignition system.
